BARB- WIRE MACHINE.

SPECIFICATION forming part of Letters Patent No, 323,488, dated August 4, 1885.

Application filed May 13, 1884.

To all whom it may concern Be it known that we, CHARLES H. BAKER and Framers L. BESTOR, citizens of the United States of America, residing at Knoxville, in

the county of Marion and State of Iowa, have invented certain new and useful Improve ments in Barb-Tire Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to an improved barbmachine.

The object of the invention is to obtain a machine by the use of which barbs may be secured to fence-wires quickly and surely; and 1 to the accomplishment of the above the invention consists of the novel devices and combination of devices, as will be described and claimed.

Reference will be made to the accompany- 2O ing drawings, in which Figure 1 is a plan of the machine, with parts in section; Fig. 2, a front elevation; Fig. 3, a side elevation; Fig. 4, a detail of parts thereof; Fig. 5, a section of wire with barb attached, and Figs. 6, 7, 8, and 9 views showing position of barb during different steps in the operation.

Like letters refer to like parts in each View. A represents the bed-plate of the machine; 13, the legs or supports upon which it is mounted, and C the main driving-shaft. Upon the outer end of shaft 0 a driving-pulley, D, is

mounted, and upon the same shaft is mounted a cog, E, which in its revolution meshes with a cog, F, keyed to a shaft, G, which has bearings in suitable boxes mounted on the bedplate, and to the opposite end of which is keyed a bevel-gear, H. This gear meshes with a bevel, I, which is loosely mounted on a spindle-like projection formed on the front end of a block, K, mounted on bed-plate A, as shown clearly in Figs. 1 and 3. From the rear to the front face of block K an opening is formed for the passage of one wire marked L, said wire passing over a sheave, M, from any suitable feeding mechanism. Block K is also cored out to accommodate a shaft, N, through the entire length of .which is formed a passage for the second wire, 0, which is also fed from any suitable mechanism. A rotary m motion is imparted to shaft N through the (No model.)

medium of a cog, I, which is keyed thereto, and passes through an opening in the bedplate to mesh with a cog, Q, keyed to one end of a counter-shaft situated below said bed-plate. To the opposite end of this counter-shaft a bevel, It, iskeyed, which meshes with a bevel, S, keyed to the main shaft 0. Upon shaft G is formed a cam, T, which contacts with an arm, U, secured to a shaft, V, which has suit-- able bearing in boxes mounted on the bedplate A, and to the opposite end of said shaft a vertical arm, W, is secured. Arm W. is notched upon one upper edge, as shown in Fig. 4, to accommodate the barb-wire, and occupies a position in front of the bevel-gear I.

By means of the arrangement last above described at certain intervals an oscillating motion is imparted to arm XV, for the purpose hereinafter described.

Mounted upon shaft N is a cam, X, prefer- 7o ably of the shape shown in Fig. 3, and which moves in aslotted arm, Y, mounted in a brackct, Z, secured to the bed-plate, and upon the front end. of this shaft is formed a wrappingterpin, a. By this arrangement at certain in 7 5 vals this shaft anditswrapping-pin are drawn back from contact with the fence and barb Wires, and then pushed forward to contact with the barb-wire to complete the wrapping.

A pin, 1), is formed upon the front face of bevel I to assist in wrapping the barb, as will be described.

'We will now proceed to give in detail the operation of our machine, and in so doing will refer especially to Figs. 6, 7, S, and 9, as showing the different stages thereof. The fence wires are fed through the passages formed in block K and shaft N, and the barbwire fed therebetween to occupy the position shown in Fig. 6, being supported in the notched upper end of arm \V. Motion is then imparted to theinain driving-shaft, and, through the medium of the gearing described, the gear I, with its wrapping-pin b, is revolved, as also is the shaft N. The pin of gear I contacts 5 with the long end of the barb wire and wraps it around the wire L, as indicated in Fig. 7, and partly around wire 0, as shown. At this point in the operation the shaft N, with its pin a, is drawn back, to prevent said pin from contacting with the barb-wire; but, the parts being properly arranged, as said pin passes below the horizontal section of said wire, Fig. 7, it will be forced out, and in its revolution will be brought into contact with the long end of the wire after the pin of gear I has left it, as indicated in Fig. 8; and upon the further revolution of said shaft the barb will be fur ther wrapped around wire 0, and occupy the position shown in Fig. 9, the two fence-wires being brought close together, as shown. At this point in the operation the cam on shaft G causes the vertical arm to oscillate to allow of the escape from the notch in said arm of the cut end of the barb as the wires are fed forward.

What we claim is 1. The combination of a shaft provided with a passage for one fence-wire and a wrappingpin, and mounted in a block through which the remaining wire is passed, a gear revolving around said shaft and provided with a wrapping-pin, and suitable gearing for revolving the parts, as and for the purpose set forth.

2. The combination of a shaft provided with a passage for one fence-wire, and with a wrapping-pin, and mounted in a block through which the remaining wire is passed, means for imparting a rotary and reciprocating motion thereto, and a gear revolving around said shaft and provided with a wrapping-pin, as described.

3. The combination of a shaft provided with a passage for one fence-wire, and with a wrapping-pin, and, mounted in a block through which the remaining wire is passed, a gear revolving around said shaft and provided with a wrapping-pin, means for rotating said parts, and an oscillating support for the barb-wire, as described.

4. The combination of gear I, provided with pin 6, and mounted on block K, through which thereis a passage for one wire, means for revolving said gear, shaft N, provided with a passage for the other wire and with a pin, a, and means for revolving said gear and shaft, as described.

5. The combination, with gear I and shaft N, constructed and arranged as described, and with means for revolving them, of cam X, arm Y, and bracket Z, as and for the purpose set forth.

6. The combination, with gear I and shaft N, constructed and arranged as described, and means for operating them, as described, of arm WV, shaft V, arm U, cam T, shaft G, and means for imparting motion to said shaft, as described.

In testimony whereof we affix our signatures in presence of two witnesses.
